Pixels to Print Size Calculator
Find the largest clean print your image can make. Results update instantly.
More file tasks
Check an image's DPI and effective PPI online without Photoshop, then verify whether its pixel dimensions are suitable for the intended print size.
How it works
A useful answer,
with the math visible.
Convert pixel dimensions into a dependable physical print size at 72–600 PPI, with inch and centimetre results. Adjust the fields above and the result updates immediately—there is no upload, account or hidden processing step.
Worked example
A 3000 × 2400 px image at 300 PPI prints at 10 × 8 in (25.4 × 20.32 cm).
How to use the Pixels to Print Size Calculator
- Enter your image width and height in pixels in the input fields.
- Select your target resolution from the dropdown menu (72–600 PPI).
- Review the calculated print size in inches and centimetres.
- Check the total megapixel count for your image resolution.
- Copy or download the results for your print specifications.
What happens under the hood
This calculator runs entirely in your browser using simple arithmetic. It divides your pixel dimensions by the selected PPI value to determine print size, then converts inches to centimetres (1 inch = 2.54 cm). The megapixel calculation multiplies width by height and divides by 1,000,000. All calculations happen instantly on your device with no data sent to servers.
Before you send the file
- PPI describes image resolution; printers often use DPI when discussing output hardware.
- Viewing distance can make lower resolutions acceptable for large posters and banners.
- Do not upscale solely to create more pixels unless you inspect the final image at print size.
Frequently asked questions
What's the difference between PPI and DPI?
PPI (pixels per inch) describes image resolution, while DPI (dots per inch) refers to printer output. For digital images, use PPI; for printer specifications, use DPI. Most printers accept 300 PPI as high-quality print resolution.
Can I use this for social media images?
Yes, but social media often uses lower resolutions. For Instagram, 72 PPI is standard, while 300 PPI is better for physical prints. This tool helps you choose the right resolution for your intended output.
How do I know if my image is high enough resolution?
Compare your image's PPI to the target. If your calculated PPI is below 300 for prints, consider using a higher resolution image or accepting lower print quality. Viewing distance matters—posters viewed from far away can use 150 PPI.
What file size will my print require?
This tool shows megapixels, not file size. A 10 MP image at 300 PPI might be 5-10 MB as JPEG, but 30-50 MB as TIFF. File size depends on compression and color depth, not just pixel count.
This calculator is a planning aid. Materials, equipment and supplier tolerances vary, so verify final specifications with the printer or carrier responsible for production.
